Use this guide to replace the display assembly of your MacBook Pro 13" Touch Bar 2019.

For your safety, drain your MacBook Pro's battery below 25% charge before starting repairs.

  1. Before starting this procedure, you must disable your Mac's Auto Boot feature. Auto Boot powers on your Mac when you open the lid, and may be accidentally triggered during disassembly. Use this guide or follow the abbreviated instructions below to disable Auto Boot. Power on your Mac and launch Terminal. Copy and paste the following command (or type it exactly) into Terminal:

    • Power on your Mac and launch Terminal.

    • Copy and paste the following command (or type it exactly) into Terminal:

    • sudo nvram AutoBoot=%00

    • Press [return]. If prompted, enter your administrator password and press [return] again. Note: Your return key may also be labeled ⏎ or "enter."

    • You can now safely power down your Mac and open the bottom case, without it accidentally powering on.

    • When your repair is complete and your Mac is successfully reassembled, re-enable Auto Boot with the following command:

    • sudo nvram AutoBoot=%03

    Is this step necessary? I can’t perform this step as I am attempting to repair water damage and need to remove logic board & most likely replace the battery.

    @mac_medic You definitely don’t want the power coming on while the board is wet. In your case, I think powering on the machine to disable Auto Boot would do more damage than it prevents. I agree, skip this step and be prepared to disconnect the battery quickly if the laptop automatically powers on. Good luck!

    This did not work when running High Sierra.

    Tried this on a 2018 MBP 13” Touchbar (there’s no iFixit guide for this model yet). Need to replace a broken screen.

    Luckily I managed to connect to an external screen (Cmd-Down Brightness to switch displays) and enter above command. Seems to work, but there’s another problem with this model - it powers up as soon as any key is pressed……. ffs <gnashes teeth>

    I unscrew the battery first and wrap electrical tape over the logic board battery connector before attempting any repairs to the board. Haven’t had any problems yet and I’ve worked on about 10 of these models already. Also when you open the bottom case use a suction cup at the bottom and pull up then run a plastic spudger along the edges to disconnect the clips. Also only use a plastic spudger on the board. Saw a youtube video from a repair shop and he did not disconnect the power and used all metal tools during the entire process of removing the board. His last step was to disconnect the battery terminal.

    Is this step necessary if my mac can turn on? Battery fully dead(

    BEFORE YOU START: The included torx head stripped off before I was done (and you might need an additional T4) so stop now and go buy a good one. Also they fail to warn you above to get some blue threadlocker ahead of time.

    This command did not work for me and I read that sometime in later 2020 Apple stopped this command from working…any ideas on a work around?

    Not able to do that with damaged screen

    Hi. This does not work on 2018 13” MacBook Pro with Touch Bar. I did exactly this to disable auto boot. But when I check by using nvram -p it says: auto-boot true. Am I doing something incorrectly? I did everything step by step. Copied and pasted the sudo command, pressed enter and then entered my password. I have Big Sur 11.1 installed. Is there any other way since I need to replace the screen. Thank you. Adrian

    • Before you proceed, unplug and power down your MacBook. Close the display and lay it on a soft surface, top-side down.

    • Use a P5 Pentalobe driver to remove the six screws securing the lower case:

    • Two 6.2 mm screws

    • Two 5.3 mm screws

    • Two 3.4 mm screws

    • Throughout this repair, keep track of each screw and make sure it goes back exactly where it came from to avoid damaging your device.

  2. Apply a suction handle to the lower case near the front-center area of the MacBook Pro. Lift the suction handle to create a slight separation between the lower case and the chassis.

  3. Insert one corner of an opening pick into the space between the lower case and the chassis. Slide the opening pick around the nearest corner and halfway up the side of the case. This releases the first of the hidden clips securing the lower case to the chassis. You should feel and hear the clip pop free.

  5. Insert your opening pick once again under the front edge of the lower case, near one of the two centermost screw holes. Give the pick a firm twist to pop free the third clip securing the lower case to the chassis. Repeat this procedure near the other of the two centermost screw holes, popping the fourth clip free.

    • Repeat this procedure near the other of the two centermost screw holes, popping the fourth clip free.

  6. Pull the lower case firmly towards the front of the MacBook (away from the hinge area) to separate the last of the clips securing the lower case. It may help to pull first at one corner, then the other. Pull to the side—not up.

    • To reinstall the lower case:

    • Set it in place and align the sliding clips near the display hinge. Press down and slide the cover toward the hinge. It should stop sliding as the clips engage.

    • When the sliding clips are fully engaged and the lower case looks correctly aligned, press down firmly on the lower case to engage the four hidden clips underneath. You should feel and hear them snap into place.

    Hab zum Schluss das Blaue OpeningTool benutzt und am Rahmen in der nut eingehackt um den Deckel final hinein zu drücken. Da er per Hand nur bis zu einem gewissen Punkt geht

    I have done 2 these these exact same 2019 MacBooks now, and both times The screw on the right seems to not be a T3. At first it appeared that I stripped it, but once I got to the second one and I was very gentle with it, it’s a totally different screw. And I can’t figure out what it is… But the T3 or the T4 will not remove it. Neither will a Pentolope. I just removed the left screw, and then I pivoted the cover away so I could remove the connecter. Anyone else having this issue?

    After doing the job the first time, when I opened the display there was something clicking loudly. I had found out that this antenna assembly wasn’t put back properly. When reinstalling this, there is a flat metal piece on the bottom centre of the antenna assembly. Mine became bent for some reason. I had to bend it back straight. It needs to click back in to top case. Problem solved!
